Sure.  That's what we have today, except that the link libraries are
named libfoo-1_34_1.so and libfoo-1_35.so.

Do you mean that application A, compiled against 1.35.0, should use
1.35.1 without recompiling?  I think that's a dangerous game given

True, and that has caused some consternation amongst the masses.

Touché!  Maybe we should build only the multithreaded variants
and see if we get any complaints ...
